This is intended to be run on URL encoded output lines from a
gpfs list policy run.  It creates panda structures that are
then saved as parquet format for ease of downstream processing.

Can be run in parallel across many inputs by wrapping with papermill
and have upstream split the input file.

Makes it slightly more resilient and forms the foundation for
the parquet notebook.

This simplifies later report running to consolidating parsing and dataframe
create operations into a single batch.
